In Praise of Rodinal (Part 1)


History 
Rodinal in one form or another has been available to photographers for over a century. Originally produced by Agfa it can now be found in many different guises Adox/Calbe/Foma RO9 all basically now the same developer.
In fact Rodinal has become a bit of a cult developer, some even make their own using Paracetamol


 Rodinal is one of my favourite developers, it is compensating when mixed in larger dilutions like 1:50 or 1:100 this also makes it very economical and to cap that it seems to last forever without going off in its undiluted state.
(although this is only true with undiluted solutions, once diluted I'd personally use the mix within the hour).


While most other developers are useless when they go a dark straw colour, Rodinal remains useable regardless of colour – I have used the stuff when it was black, just take a look at the picture at the top of this article.
I can find no difference in developer activity between new bottles and ones where the solution is the same colour as Cola!


I first used Rodinal in the early 1980's when I worked with a photographer who demonstrated its qualities on a roll of APX developed at 1:50 shot on his 1950's Rolleicord.
At the time I thought he was quite mad as he decanted the tiny amount of black liquid from what looked to be an old brown glass medicine bottle with rubber stopper.
His results were wonderful, with a long range of tones and very sharp, it wasn't long before I had purchased my own bottle (though it came in a plastic bottle)


Rodinal apart from lasting longer than most photographers life spans, also has the advantage of being very economical as it can be used highly diluted 1:50 (1 part concentrate to 50 water) being my favourite; but anywhere between 1:25-1:200 can be used as long as you don't use less than 10ml of concentrate according to Agfa guidelines.
In reality those are pretty conservitive and I use 5ml as my minimum, and this seems to work well as my developer tank needs 500ml for a 120 film so the maths isn't too hard.

Above is the classic combination of APX developed in Rodinal 1:50

Recently the producers of Rodinal have lost the right to the name as a trademark, I have it on good authority that it is produced in the same factory in Germany but is now known as R09 'one shot' the new label seems to state it quite clearly:

Produced as Rodinal for Connect Chemicals (ringed in red) for any that harbour doubts. In  part 2 I'll give some more examples of Rodinal in practical use as well as possibly showing some tests of how it differs from other developers, results from pushing film, and why I feel it makes a good choice for stand development.

Hy,

I would really like to see your tests with rodinal...

Oh... and great blog!

I've used Ilford's DDX, Kodak's xtol and a few others here and there. Somehow, I always gravitate back to Rodinal 1:50 and 1:100 low ag. It just seems to do all I want. And at those dilutions, the price is really a show-stopper...(NOT!)
;)

I've used DDX and Ilfotec HC and they're great especially DDx for a bit of speed increase.

DDX is expensive though, and Rodinals long life is just too good to be true, coupled with stand developer without artifacts makes Rodinal my main choice.
Last night I developed a roll of TMY at 1:100 for an hour.
The first half of the roll was snow in bright sun, the second half was indoors- Rodinal handled it with ease.
For me that is the developers 'ace in the hole'.
More of that in part two early next year!

There is something about Rodinal that makes me coming back to it over and over again. It's not just sharpness, price, longevity, ease of use, flexibility or anything in particular, but rather all those things put together plus a something else, some 'undefinable' element, perhaps in the realm of what people usually refer to as 'tonality'.

I'm very much interested in part II of your essay- especially wondering if you're going to touch on that same undefinable element that I feel is there.

Just some blabbings of mine.

Great blog, as ever.

Best, Sander.

Thank you Sander, Rodinal is a great developer, it has its detractors which often polarizes opinion.
The reasons I use it are its flexibility and overall look of the mid tones-the tonality you mention is not a myth, not in the Zeiss glow (although I like Zeiss lenses too)way.

I'm not sure I'll be able to track down the undefinable magic,-I guess those who see it can utilise it-even if we can't always explain it!
